Well I used three different blades in three different razors, all blades were first time to use them.
1.) was a Personna Med Prep in a Gillette Red Tip
2.) was a Polsilver in a Gillette slim adjustable set on 3
3.) was a Gillette Silver Blue in a Gillette Tech for touch-up work.
by the way it was a super BBS shave which is happening more often now that my technique is improving.
